After i downloaded these softwares like Microsoft AntiSpyware,Spybot Search & Destroy,Spyware Doctor and SpywareBlaster from http://nod32.com ,http://downloads.com ,http://www.javacoolsoftware.com/spywareblaster.html ,http://opera.com to fix the prpblem of spam , spyware ,virus and trojan. My laptop's run slower than before even too slow, sometime it stops running, operating and no answer for my command. The other problem is when i just log on into my computer then the Spybot Search & Destroy software was running and scanning automatically.Later when it finished scanning this warning message coming up :" Some problem couldn't be fixed.The reason could be that the associated files are still in use (memory).This could be fixed after a restart.May Spybot S&D run on your next systerm start". And the problem could be fixed by the name " ISTbar.Slotch" Can you help me to solve it. Thank in advance for any help. Thank you
